Specification of Letters Patent.

Patented Jan. re, 11ers.

To all whom it may concern Be it known that I, ALFRED F. MORENCY,citizen of the United States of America,

residing at Sturgis, in the county of St.

to reduce the velocity of the water after leaving the feed or supplypipe, thereby eliminating the usual noise incident to the flushingoperation, particularly where, a

high pressure water supply is utilized.

With the above general objects in view, the invention may be definedfurther astconsisting of the combinations of elements embodied in theclaim hereto annexed and illustrated in the drawings forming a parthereof wherein Figure 1 is a side elevation of the invention partly insection. Fig. 2 is a horizontal section taken on the line 2-2 Fig. 1.

Referring more specifically to the draw ings in which like referencenumerals designate corresponding parts in each of, the views 1represents the bottom of a flush tank of usual construction apertured asat 2 to receive a flange supply pipe 3 having its outerend connectedwith a suitable source of water sup ly (not shown), and the inner endthereof secured to the lower end of a ,water feed pipe 4.

- A truncated cone shaped valve seat member 5 screwed upon the upper endof the pipe 4 is provided with a central opening 6 coincident with thebore of pipe 4. This opening 6 is normally closed by a cylindrical valve7 seating upon the edge 8 of the wall 9 surrounding said opening 6. Thevalve 7 has the upper portion thereof closely embraced by the contractedupper end 10 of casing 11, which in turn is secured to the outer annularwall 12 of the truncated cone shaped member 5 as by screw threadedconnection 13.

As best shown in- Fig. 1, the casing 11 has anenlarged or bulged portion14 extending both above and below the valve seat 8 forming an expansionchamber 15 for a purmember 5 is provided with a screw threaded portion16 adapted to receive the upper end,

of a correspondingly threaded tube 17 surrounding and concentricallylocated with respect to the feed tube 4. The tube 17 terminates at itslower end a short distance above the bottom 1 of the flush tank, and atits upper end communicates with the expansion chamber 15 througharc-shaped peripheral-openings or slots 18 formed in the member 5,

Any suitable mechanism may be employed for operating the valve 7, but inaccordance with the present embodiment of my invention the casing 15 isformed with oppositely disposed upwardly curved arms 19 and 20. The arms19 and 20 are forked and the former arm projects considerably above thelatter. A lever 21 is pivoted at one end between the forks of the arms20 and has its other end projecting through the forks of the arm 19 andits intermediate portion projecting through the upper looped end 22 ofthe valve 7. A float lever 23 is pivoted intermediate its ends to thearm 19 and is connected to the end of lever 21 by means of a link 24:.It is" of course understood that the long end 25, of the float levercar- -ries a float (not shown).

With the parts in the position seen in Fig. 1, the lowering of the end25 of the float lever 23 causes the valve 7 to rise from its seat. Asthe valve opens, water rushes from the feed pipe 4 through opening 6formed in member 5 into the chamber 15, Where the force of the water ismore or less dissiplated, and from this chamber passes out t rough theopenings 18 down thewalls of tube 17 finally discharging into the flushthan the diameter of the feed pipe 4, the

water flowing down through the tube is spread over a comparatively largearea and consequently the operation of the invention is practically anoiseless one. Moreover, it will be noted that the water in the chamber15 surrounding the valve seat drops back into the tube 17 with apressure evenly distributed around the seat.

In practice it has been found desirable to make the tube 17 of such asize that the space between the tube and the inclosed feed pipe 4 willbe somewhat greater in area than the intm'ior of the feed pipe,.but I 10prising a coupling adapted to pass through the bottom wall of a tank andbe rigidly securedthereto, a stand pipe detachably connected to andsupported by said coupling, a cap threadedly engaging the upperextremity of said stand pipe and provided with an opening extendingthereth'rough; the end of the walls forming said opening forming a valveseat, a second pipe embrac ing said stand pipe, threadedly engaging thesaid cap and terminating short of the said coupling, a cylindricalmember with outstanding integral armssecured to the outer periphery ofsaid cap'and provided with a central opening extending through the topthereof, a cylindrical plunger valve member slidably disposed withinsaid opening and adapted to rest upon and closesaid valve seat, meanspivotally secured'to' ca said integral arms adapted to actuate saidvalve member, said cap provided with openings for establishingcommunication of said second pipe with said cylindrical member.

In testimony whereof I aflix my signature in presence of two witnesses.
